ORCHARD-HEATER.

-tui-ecl, Y compactly packed for shipment,

easily and quickly assembled when put into use, readily charged withfuel' and ignited; in which the combustion may be perfectly controlled,and which when assembled is weather proof. l

My invention embodies .a 'fuel container stamped or drawn up of a singlepiece of lsheet metal into the form of a seamless pan, and provided witha domeshaped cover` which may be secured to said pan by being snappedthereon. The dome shaped cover has la central opening -to receive aloose, vertical, perforated flue, capable of being set upright toproject above the dome shaped cover and serve as a draft chimney whengreat heat is desired, 'or of being re moved -from lthe chimney positionand laid' horizontally in the bottom of the fuel pan Where yitfacilitates .the burning .when a` smudge or slow combustion is desired.The

dome shaped cover is made in two parts,-

one to revolve upon the other, both parts being perforated withregistering openings for regulating the draft by the movement of 'oneupon the other to close and open the ports. A supplemental dome shapedcap is provided for closing the central opening in the cover to make theheater entirely rain proof and also to close the combustion chamber soIthat the slow combustion as in smudging may be edectively regulated bymeans of the registering parts, and s'aid My invention also 'consists inthe novel construction of parts and devices and in the novelcombinations of parts and devices herein ldescribed andV moreparticplarly specified in the claims. l i Vln the accompanying drawingforming a part of this specification, Figure l is a top or plan view of`the improved heater assembled, showing the cap for the openuSpecification of Letters Patent. Application led June 12, l1911.. SerialNo. 632,547.

I ing in the dome shaped cover applied as when the heater is closedagainstrain. Fig. 2 is a vertical-section taken on the line 22 of Fig.1, excepting that in the section the cap` is removed and the verticalcylindrical perforatef draft chimney is shown as erected. Fig. 3 is ahorizontal section on the line 33 of Fig. 2; Fig. 4

'is a'section similar to Fig. 2 but showing .the cylindrical draftchimney laid in the horizontal position onthe bot-tom of the fuel pan. ll

.In said. drawing, A is the circular fuel containing pan made of asingle piece of metal and with slightly flaring sides so that `a numberof them may be readily nested together for shipment.' Its upper edge isst-ilfened with a false-wiring a.

v- B is one member of the dome shaped cover and is made with a dependingbeaded flange b adapted to snap down fricl tionally outside of and overthe false wire edge a of the fuel pan. A central opening C ismade in thedome shaped member B, the edges of which are at this point, flangedupwardly to form a vertical wall c. second dome shaped 1member D alsowith a central flanged opening is applied to fit down over the flange of.the member B, and is secured thereto by the turning over ofy theflange, the construction' being such that the upper dome-shaped memberD' may be turned readily upon' the dome shaped 'lower member B. Boththe'dome shaped lower member B and the dome shaped upper member D 'areperforated with corresponding ports E, the dome shaped upper lmemberhaving also, at some of its ports, upturned finger holds e, by which toturn it. By turning the upper member, D on the dome shaped member B theports E may be partly or wholly opened or closed to regulate the draftas desired, and to close the fuel chamber against the weather.

The draft chimney is shown at F, and consists of a flat p iec'e of sheetmetal formed into cylindrical shape and hooked tog-etl'ier at the looseseam Then unhooked, a

,number of these chimneys may bev nested together for shipment. Thisdraft chimney is perforated'at short intervals with holes so thatwhenerected there may be free communication for the air from the fuelpan' -to the interior ofthe chimney above the fuel, and thus free escapeto the outer atmosphere for the products of combustion. When it isdesired that the burning shall be rapid, as in case of severe frost,t-he chimney is erectedinto the position shown in Fig.

2. But when the heater is to be closed up pan, some part of it, as thefuel is consumed,'

Will project above the surface line H of the liquid fuel or oil. Thetendency of the oil is to cling to the surface of the metal of thechimney and burn there. And the perfo-rations in the chimney' While inthis horizontal position Will thus aid to maintain a more regular slowcombustion for purposes of smudging. vFor this purpose of smudging theoutlet and. inlet of air may be regulated by applying the supplementalcover to close or partlyclose the central opening and` adjustingtheregister ports to a greateror less degree of closure.

l. An orchard heater comprising in combination the following parts afuel pan,I a

cover for the pan having a central opening,

and a vertical draftchimney having perforated sid'es, said d raftchimneybeing loosely inserted through the central 'opening in the cover andvadapted to be removed therefrom and laid horizontally inthe fuel pan,sub

stantially as specified.

2. An orchard heater comprising, in comhina-tion: a fuel-pan; and aremovable cover, said cover comprising two parts each'provided with a.central perforation and With ports adapted to register for regulatingthe draft, one of the parts being provided With integral means vforretaining the two parts in position, substantially as' specified.

3. An orchard heater comprising, in combination: a fuel pan, a removablecover the latter comprising t-Wo" members relatively rotatable and each.provided With ports adapted to register, whereby the draft may beregulated, and a detachable vertical draft chimney extending-down in'tothe fuel pan, substantially as' speciied; Y

4;. An orchard heater comprising, in combination: a'fuel pan having astrengthened upper edge, a two-part dome shapedcover havingl a dependingiange adapted to engage and snap over the upper edge ofthe fuel pan andto be retained in position thereby,` said cover having a cent-'ralopening and the tivo partsthereof having ports adapted to be broughtinto registry Wit-h each other, a removable perforated draft chimneyadapted to be inserted upright in said central opening or laid in ahorizontal position in the fuel pan beneath the cover, and asupplemental cover adapted -to close the chimney opening in the coverWhen the chimney is placed entirely within the fuel pan, substantiallyas specified.
